Baby boy’s on his way! Kim Kardashian opened up about her second pregnancy via Twitter on Sunday, July 19, revealing that she’s gained 20 pounds in almost 20 weeks. 

“Went to the Dr today for a check up, guess I was off on my 20 week mark by a week or two... But not the 20 lbs LOL,” the mother of North West tweeted. 

Kardashian and her husband, Kanye West, are expecting a son in December. The reality star, 34, made headlines during her first pregnancy for her weight gain, but in her second time around, has thus far barely shown a baby bump in her form-fitting ensembles. 

The business lady now also has a new trick for dealing with morning sickness — a pill called Diclegis, which she endorsed via Instagram. 

“OMG. Have you heard about this?” she captioned a selfie holding up the pill bottle. “As you guys know my #morningsickness has been pretty bad. I tried changing things about my lifestyle, like my diet, but nothing helped, so I talked to my doctor. He prescribed me #Diclegis, I felt a lot better and most importantly, it’s been studied and there was no increased risk to the baby. I’m so excited and happy with my results that I’m partnering with Duchesnay USA to raise awareness about treating morning sickness. If you have morning sickness, be safe and sure to ask your doctor about the pill with the pregnant woman on it.”

All her morning sickness and pregnancy struggles were clearly worth it, as the proud mom posted some cute pics of little Nori, 2, eating a chocolate chip pancake on Sunday. 

“Before…,” she captioned one shot of North pressing the treat to her face. “After…,” she wrote on a shot of North with chocolate smeared across her mouth.
